\caption{\label{tab:tab_k1}\textbf{Coefficient Estimates from Figure K.1}: This table reports the estimated coefficients and associated standard errors, computed based on a block-bootstrap procedure, which are
used to produce Figure K.1. To compute the results for each type of lobbying activity, we identified all dyads where a particular company donated to a particular Senator for the first time in at
least eight quarters. The number of observations is 12,232,896 firm-politician-quarter dyads. For
Any Lobbying, Lobby Sponsor, Lobby Cosponsor, and Lobby Committee, there are 16,860, 4,426,
13,062, and 16,411 such instances, respectively.}
